APPLICATIONS
The 830-004 is a single output isolated DC/DC
converter with an input range of 110 to 375 Vdc. This
allows the module to operate from any rectified 80 to
265 Vac line, corresponding to line voltages found
worldwide. Fixed output voltages between 5 to 18 Vdc

are available to suit a variety of applications. Low cost,
high reliability and small dimensions are the main
characteristics of this design. The use of an advanced
PWM provides for stable and efficient operation over a
wide load range.

TYPICAL CONFIGURATION
APPLICATION NOTES
Model 830-004 is a complete DC/DC module based on
a flyback circuit topology.
Most applications require the addition of output
capacitance. The capacitor’s voltage rating should be
selected in correlation to the output voltage of the
830-004. Choose sufficient capacitance to reduce the
output ripple to an acceptable level for the application.
A 47µF electrolytic should generally be suitable and
should be located close to the output pins.
To operate from an AC line, a bridge rectifier must be
added. A DB104 bridge rectifier or four IN4005
configured as pictured.
Diodes should be 600 volts, 1 amp and should be used
in conjunction with a 47µF input capacitor. Choose the
capacitor voltage rating appropriately. For example,
117 Vac generates 165 volts peak. At a 1.5 x derating,
use a 250 volt capacitor.
